Is there a python difflib.get_close_matches("targetString", array) equivalent in Ruby?

Question

Is there a method in Ruby similar to Python's difflib.get_close_matches("<target_string>", "[<array_of_strings>]") method?

Answer 1

An approach would be

$ gem install amatch

ruby> require 'amatch'
  ==> true

ruby> "a bee sat on my knee".damerau_levenshtein_similar("a bee sat on my knee")
  ==> 1.0

ruby> "a bee sat on my knee".damerau_levenshtein_similar("a fly sat on my knee")
  ==> 0.85

ruby> "a bee sat on my knee".damerau_levenshtein_similar("a BEE sat on my knee")
  ==> 0.85

ruby> "a bee sat on my knee".damerau_levenshtein_similar("a BEE sat on my knee".downcase)
  ==> 1.0

ruby> "snow".damerau_levenshtein_similar(["flow", "snowmobile", "sonw"])
  ==> [0.5, 0.4, 0.75]
